Abstract

A cleaning device (20) has a nozzle section (21) constructed from a supply nozzle (211), a suction nozzle (213) having the tip located at a position vertically slightly below the tip of the supply nozzle (211), and an overflow nozzle (215) having the tip located at a position vertically slightly above the tip of the supply nozzle (211). The area of the inner diameter of the supply nozzle (211) is greater than the area of a portion where reaction liquid and cleaning water are held. The supply nozzle (211) is placed so that a gap is formed between the outer wall surface of the supply nozzle (211) and the entire inner wall surface of a reaction container (C), and the gap allows cleaning water supplied from the supply nozzle (211) to flow through it. The cleaning water supplied from the supply nozzle (211) flows through the gap and is sucked by the overflow nozzle (215).
